Various bits of code for ESP8266

esp8266's Issues

give rBoot it's own repo

I've been using rBoot for a couple months now and I'm pretty much sold on it.

Now I'm just getting to the point I'm cleaning up my first project using it and with any
luck will be using it in an upcoming client project. With that it would be super handy
to have rBoot at a git submodule, but that requires it being in its own repo.

Hopefully this isn't an issue, thanks for you work on this, it's vastly improved my workflow.

Error on compile

Hi
I am receiving error upon compiling.

This was building sometime back.

OTA leads to corrupt ROM

This is most likely due to lack of understanding surrounding the linker scripts. These are the steps I've performed, it all seems to make sense but in practice the update fails, while reporting success.

I'm using an ESP8266-03 from Electrodragon with 512k of flash. I'm using the rboot-sampleproject as my starting point.

Modify rom1.ld

$ head rom1.ld 
/* This linker script generated from xt-genldscripts.tpp for LSP . */
/* Linker Script for ld -N */
MEMORY
{
  dport0_0_seg :                        org = 0x3FF00000, len = 0x10
  dram0_0_seg :                         org = 0x3FFE8000, len = 0x14000
  iram1_0_seg :                         org = 0x40100000, len = 0x8000
  irom0_0_seg :                         org = 0x40242010, len = 0x3C000
}

Changed irom0_0_seg in rom1.ld from 0x40282010 to 0x40242010

esptool2 doesn't return 0 on success

Esptool2 doesn't return anything on success, which make interprets as a failure (on linux at least). This terminates the build attempt, but by repeatedly running make you can get it to finally build.

rboot-ota/rboot-ota.c contains HTTP example code

In rboot-ota/rboot-ota.c contains HTTP receive parsing code that IMO belongs to the rboot-sampleproject. I think rboot-ota/rboot-ota should only contain code that is about writing (chunked), switching roms, etc.. The actual download should be left to the user and should be in rboot-sampleproject.

Furthermore the HTTP response parser is very assumptious about how the data arrives, it expects the entire header to arrive all at once. But of course there is no guarantee this will happen. For instance when using SimpleHTTPServer from python all the header lines arrive one by one resulting in failed upgrades. But then again if this code is not part of rboot-ota anymore then it is not that big a deal as it is an exercise left to the user.

NodeMCU v2 and SDK v1.2.0: add -fm dio to esptool.py in readme.txt

I have rboot working on NodeMCU v2 with SDK v1.2.0. The most important thing for the ESP-12 used on NodeMCU v2 is to add -fm dio to the esptool.py command line. I think this might be worth warning for in readme.txt?

Order of operations - NTP before mDNS breaks mDNS

Strange issue I found using the NTP client as attempting to register on mDNS.

When NTP is called before mDNS, mDNS fails. If NTP is called after mDNS, it works just fine. I suspect that there is an issue with the SDK mDNS or UDP/epconn functions.

Submitting it here as more as FYI/documentation of the interaction.

DS1307 - Supply Voltage

Reading your comments on the DS1307 being flaky, I think it should be noted that it doesn't run from 3v3 - its a 5V part. DS1307 is not suited to for a ESP8266 (I now have 5 useless clocks! :)

The latter device can run in the range of 3v to 5v

Second reset fails

UPDATE : issue corrected, my own code was overwriting in the middle of the flash.
Issue closed, sorry for any inconvenience.

I created a .bin and loaded into flash, it contains the rboot image and the executable. The first time I push the reset button the code starts up correctly. When I push the reset button a second time, the bootloader tells it didn't find any correct rom image. I guess the first reset creates a config entry at 0x1000, which the second reset tries to use.

Project can be found here : https://github.com/vortex314/esp_gtw

I'm using a nodemcu module 32mbit.

undefined reference to rBoot

How do I resolve this?

Bug in rboot-ota.c:upgrade_recvcb()

There appears to be a small bug in the upgrade_recvcb() function of rboot-ota.c. On some servers it appears that the first chunk just details information about the file that will be downloaded (e.g. does not contain any actually rom data). Subsequent chunks actually contain the data. So the check below:

if (upgrade->totallength == 0) {

is not a good check because when using a simple Python server to serve up the roms the totallength is still set to zero (0) after the first chunk of the download has been processed (e.g. length -= (ptrData - pusrdata) == 0). So the second chunk isn't processed correctly. My fix was to key off the "sumlength" field that will be zero prior to the first chunk and non-zero on subsequent chunks.

if (upgrade->sumlength == 0 ) {

Perhaps not the most elegant fix but it seems to work for me. I've been able to integrate the rboot OTA mechanism into my Sming-based project.

i have problem with WiFiClientSecure :(

hi
i am thanks for your help to peaple for publishin your good project
in this code i want give data from google Sheet and send data in telegram bot,
i use this project to give data from google sheet:
https://github.com/lorol/Googlesheet_DHT_simple
and use this project for recive and send data from telegram robat:
https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot
i use esp8266
i merge two above project but i cant compile because i give error , because two project use WiFiClientSecure.h library , and same client :(

i changed the client name , and code ha been compiled, but in serial monitor , program crashed
i changed "HTTPSRedirect* client= nullptr;" to "HTTPSRedirect* test= nullptr;" and change every client in the code to test,
i also change below code, in the next change

WiFiClientSecure client;
UniversalTelegramBot bot(BOTtoken, client);

to :

WiFiClientSecure test;
UniversalTelegramBot bot(BOTtoken, test);

and you can see my Serial monitor in both time:

Make file error

Hi,

Thanks for your great project. But I couldn't get it worked. I always get this error

FW build/rboot-hex2a.h
make[1]: /opt/esp-open-sdk/esp8266/esptool2/esptool2.exe: Command not found

I am not a linux guy, but I am using a ubuntu VM. I know the esptool2.exe is there but it is not compiling it.

Could you please help on this?

Thanks.

Commit bba5f02 breaks rboot-sampleproject using ESP-01

This appears to be related to the updated ld scripts and I can't figure out why but the ESP-01 no longer boots (zero output - not even rboot) starting at this commit. Works as expected if compiled using the previous commit. Maybe I have to update the other ld scripts in rboot-sampleproject?

OTA - Firmware update failed!

Hi Richard.

I edited the rboot-ota.h:

// ota server details
#define OTA_IP { 192, 168, 0, 42 }
#define OTA_PORT 8080
#define OTA_ROM0 "rom0.bin"
#define OTA_ROM1 "rom1.bin"

I opened the terminal:

What is wrong? How I can debug?

new ld scripts for SDK 1.1.0 (rboot-sampleproject)

SDK 1.1.0 ld scripts has new sections in them (various ExceptionVector).

Running rboot-sampleproject that is compiled and linked using current rom*.ld and SDK 1.1.0 causes exception to be printed on serial monitor.

Booting rom 0.
Fatal exception (0):
epc1=0x40106f38, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

0x40106f38 is call_user_start on that rom0.elf

Using the new ld scripts from SDK 1.1.0 to compile and link them allow successfull running of the sampleproject.

on the latter rom0.elf call_user_start is on 0x40100004

OTA and slot 0

I'm probably doing something wrong, but I'm stuck.

I have my own code that updates the flash area of the firmware for OTA updates.

It uses the spi_flash... functions from the 1.4.1 SDK to erase and write the flash sectors.

Using an ESP-1 module I write the fw to 0x2000 (slot 0) and 0x42000 (slot 1) (linked with their own corresponding linking script) with esptool.py

That goes well. I can then switch between them and both copies of the fw work.

If I run from slot 0 I can then erase and write fw to slot 1 and switch with no problems.

If I run from slot 1 when I try to erase slot 0 I think the memory gets corrupted. It doesn't finish the erase and I get:

Erasing 56 sectors starting with 0x2

Unless I am miscalculating the flash sectors I don't see how this would happen.

This is on a ESP-1 so I'm assuming 512KB flash.

Any suggestions on what I should look at?

Thanks,

Alberto

rBoot in Sming

How do I implement rBoot in any of the examples in Sming framework? Can you tell me the steps involved?

OTA failure: Broken pipe

First, thanks for working on the bootloader! I've definitely thought about having >2 ROMs but I didn't feel comfortable embarking on such a project on my own.

Unfortunately, I've run into some troubles. Here's what I'm seeing:

1. ESP connects to the wifi network
2. ESP sends the GET request for the new firmware
3. Webserver (Flask) receives the GET request
4. Webserver responds with 200
5. Webserver throws a "Broken pipe" exception

Here's the call stack:

Traceback (most recent call last):
  File "/usr/lib/python2.7/SocketServer.py", line 593, in process_request_thread
    self.finish_request(request, client_address)
  File "/usr/lib/python2.7/SocketServer.py", line 334, in finish_request
    self.RequestHandlerClass(request, client_address, self)

    self._sock.sendall(view[write_offset:write_offset+buffer_size])
error: [Errno 32] Broken pipe
----------------------------------------

Is this the "python server" that sends headers in multiple chunks?

FOTA example

Hi Richard.

I am developping with Unofficial Development Kit for Espressif ESP8266 and I want to add FOTA feature in our project.

I am studing the rboot-sampleproject, but this error occurs:

Do you have a tip?

restart on rBoot-sampleproject does not always restart

I've been playing with rBoot-sampleproject and overall it works great. OTA update is smooth. Sometimes, however, restart is not successful. Here is an example output from the usb serial port with the original code, unaltered in function from the git repository:

    V1 available commands
  help - display this message
  ip - show current ip address
